//Pluviometer installed at Jülich//


===== Principle =====
The OTT Pluvio 2 is a precipitation gauge basing on a weighing measurement principle. It detects both liquid and solid precipitation by weighing the bucket content. The following values are recorded:
  * intensity
  * accumulated intensity
  * bucket filling level
  * temperature load cell




===== JOYCE-CF Standard Operation Procedures =====

  * Temporal resolution 1 minute
  * Precipitation amount 




===== Data availability =====

Data are available on request, please fill the {{ :joyce_data_request_form.pdf |data request sheet}} and send it to [[mailto:info@joyce.cloud|info@joyce.cloud]].
